Hi, I have a question regarding smoking times. I'm planning to smoke about 25lbs of tri tip in my 18" camp chef smoke vault (looks like a rectangular vault), they are roughly 4 pieces of 6lbs. or so each. The temp will be roughly 225. Can anyone give me just a ball park of what I can expect in terms of cooking time? Its hard for me to imagine its the same time as one piece at 6 lbs. I'd like it to reach about 140. If its been addressed on another thread, my bad, I can't seem to find it. Thanks.
